Specification of Letters Patent.

' Patented Nov. 16, 1909.

Application filed January 13, 1908. Serial No. 410,501.

To all whom it may concern:

Be it known that I, ELMER N. CHILns, a citizen of the United States,residing at Perry, in the county of Dallas and State of Iowa, haveinvented a certain new and useful Horseshoe-Call: Former, of which thefollowing is a specification.

The object of my invention is to provide a device of the classdescribed, of simple, durable and inexpensive construction.

More specifically it is my object to provide a device of this class inwhich a previously heated horse shoe may be placed by the operator, anda calk formed on the heel thereof by the manipulation of a single lever,and either a blunt or a sharpened calk may be made quickly and easily,and with a minimum of applied power by the operator.

A further object is to provide means whereby the device may be quicklyand easily adjusted so that it will form calks either blunt or at anydesired taper, to sui the requirements of the operator.

My invention consists in the construction,

arrangement and combination of the various parts of the device, wherebythe objects contemplated are attained, as hereinafter more fully setforth, pointed out in my claims and illustrated in the accompanyingdrawings, in which- Figure 1 shows a side elevation of the completedevice embodying my invention. Fig. 2 shows a rear edge View of same.Fig. 3 shows a front edge view of same. Fig. 1 shows a verticalsectional view on the line l l of Fig. 3. Fig. 5 shows an enlargeddetail view of the upper portion of the device, along the same line asthat on which Fig. 4 is taken, showing the various parts in adjustedpositions. Fig. 6 shows a detail sectional view of'the swage-block. Fig.7 shows a similar view with a modified form of face block appliedthereto, andFig. 8 shows an enlarged detail sectional view on the line88 of Fig. 1.

Referring to the accompanying drawings, I have used the referencenumeral 10 to indicate the base of the device. Fixed to said base aretwo parallel uprights 11 having at their tops a flat face block 12.Mounted beneath the block 12 near the top of the uprights, and adjacentto the rear side thereof is a shaft 13 having fixed thereto a cam 14.

This cam is designed to be operated by means of a lever 15 pivotedbetween the uprights 11 and provided with a roller 16 to engage the cam.It is also provided with a cross piece 17 to engage the rear surface ofthe cam.

The lever 15 is operated by means of a rod 18 adjustably connected withthe lever 15 and attached to a foot lever 19, which lever is fulcrumedto the standard 10 and is normally held in an elevated position by meansof a spring 20. The said shaft 13 is designed for the purpose of movinga swage block hereinafter described.

Pivotally supported upon the shaft 13 are two mating brackets 21. Thesebrackets are provided with upwardly and rearwardly extended portionsforming swage block guides, and they are provided with ribs 22 guidingthe swage block. These ribs are clearly shown in Fig. 2.

The outer ends of the brackets 21 are connected by means of a bolt 23,which forms a stop for limiting the upward movement of the swage block.

Projecting from the forward edges of the brackets 21 are the lugs 24:for purposes hereinafter made clear. These brackets are adjustablyclamped to the uprights 11 and passed through the segmental slots 26 inthe brackets. The swage block which is shown in detail in Fig. 6comprises a body portion 27 having its sides shaped to fit between theribs 22 as shown in Fig. 2, and provided with an opening 28 at its upperend. Its lower end is provided with a flat face 29 designed to standsubstantially parallel with the block 12, and its front face is arrangedsubstantially vertical, and it is provided with a recess to receive aface block.

The face block comprises a body portion 30 shaped to fit into the recessto prevent it from turning relative to the swage block. I have providedfor detachably supporting the face block by means of a screw 81 passedthrough the swage block from the rear, and seated in the face block.

In Fig. 7 of the drawings I have shown a face block of modified form inwhich the working face thereof is arranged on a different angle from theone shown in Fig. 6, and the advantage of this will be hereinafter moreparticularly described.

I have provided for moving the swage block toward and from the block 12by means of the cranks 32 keyed to the shaft 13 and connected with links33 attached to a bar 34, which bar extends through the opening 28 in theswage block. By thisarrangement, the operator may by placing his foot,upon'the footleverlS force the swage block down toward the block 12 andwhen pressure on the foot lever 19 is released, the spring 20 willelevate the swage block until it strikes the bolt 23. By manipulatingthe bolts 25, the operator may obviously vary the angle of the swageblocks, the advantage of which will be hereinafter made clear.

The swage block is provided forthe'purpose of clamping a shoe inposition, and also for providing one face against which the calk may beformed. In order to bend the calk over against the face of the swageblock, I have provided a roller movable up and down to engage the horseshoe and force it against the swage block. This roller and itsassociated parts are all mounted in a guide frame 35, which frame issupported by means of trunnions 36 mounted in the lugs 24, so that thelower end of the frame may swing forwardly and rearwardly relative tothe uprights 11, as clearly shown in Fig. 5.

Slidably mounted within the frame 35 is the roller supporting block 37.This block is mounted in grooves formed in the frame 35 so that it isheld in line with the frame 35 during its up and down movement.

The calk forming roller is indicated by the numeral 38 and is providedwith trunnions '39 mounted in the block 37. This roller is arranged forfree rotation and the major portion of it is located in a recess in theroller supporting block 37 as clearly shown in Fig. 5. Its upper rearface, however, is exposed so that when the roller is elevated it willengage the heel portion of a horse shoe and bend it upwardly and againstthe face of the swage block as here inafter described. Obviously, if theframe 35 is in a substantially vertical position, the calk formed by theroller will be blunt. If the lower end of the frame 35 is tilted awayfrom the uprights 11, then a calk formed by the roller will be tapered,the degree of inclination of the taper being dependent on theinclination given to the frame 35.

In order that the operator may quickly and easily tilt the frame 35, andsupport it in any position of its adjustment, I have provided a shaft 40mounted in the uprights 11 and provided with a lever 41. A crank arm 42is fixed to the shaft 40 and ispivotedto a link 43, which latter ispivoted to the lower end of the frame 35, hence by a manipulation of thelever 41, the frame 35 may be tilted. I have also provided means forlockingthe lever in various positions of its adjustment by means of thespring actuated pawl 44 connected with the lever, and designed to co-actwith a notched sector 45 mounted on the adjacent upright 11.

Connection between the link 43 and the frame 35 is made adjustable bymeans of the nuts 46, so that the degree of inclination of the frame 35may be varied if the pawl and sector do not provide sufficientadjustment for this purpose.

The means for vertically moving the roller block comprises a lever 47fixed to a shaft 48 mounted in the lower end of the frame 35. Betweenthe sides of the frame 35 is a crank arm 49 on the shaft 48, and pivotedto the crank arm 49 is a link 50 hm ingits upper end pivoted to theroller block. I

have provided for limiting the upward plate is as follows: lVhen a horseshoe is placed on the blocklQ, it is extended forwardly until it strikesthe gage plate. Then it is clamped in position by means of the swageblock, and then when the roller is moved upwardly, it is bent toward theswage block. Obviously, by adjusting the gage plate, calks of greater orless length may be made, and all of the calks made on the machine whenthe plate is in one position of its adjustment, will be-of uniformlength. I have also provided simple and easily operated means forcutting off the ends of horse shoe calks as follows: Mounted on thefront face of the frame 35 is a stationconnection, I have provided anadjustable gage by which horse shoe calks may be cut off at uniformdistances relative to the body of the shoe as follows: Adjustablymounted upon the sides of the frame 35 is a gage frame 58 having a crosspiece 59 designed v to stand adjacent to the front of the frame 35 nearthe cutting blades. 7 frame is made adjustable by means ofbolts Thisgage 60 passed through slots 61 in the gage frame,

and seated in the sides of the frame 35. In use, the operator places theunder surfaces of a shoe against the cross piece 59 of the gage frame,and permits the calks of the shoe to projectbetween the cutting blades,and he holds it in this position while the roller block is beingelevated. Obviously, all of the calks cut ofi by the device when thegage frame is in any certain position of its adjustment, will be ofuniform length and by adjusting the frame, the length of the calks maybe varied.

In some instances calks that are formed by the machine are of differentlengths and it is sometimes desirable to cut them off even if they areboth of the same length in order to get a smooth and even end. When itis desired to cut them off, the operator grasps the horseshoe in a pairof pince-rs and holds the horseshoe against the gage with the calkprojecting between the cutter blades.

In practical operation, and assuming that it is desired to formhorseshoe calks with blunt ends, then the operator adjusts the rollersupporting frame in a substantially vertical position, and he alsoplaces a face block on the swage block that will have a substantiallyvertical working face. He then adjusts the gage plate 53 to suchposition that the calks will be formed of the desired length. He thenpreferably heats a horseshoe and inserts it from the rear of the machineupon the block 12, until it strikes the gage plate 53. He then lowersthe swage block until it firmly engages the horseshoe. He then causesthe roller to move upwardly until it strikes the end of the horseshoe,and when the upward movement is continued, the end will be bent up bythe roller and pressed between the roller and the swage block to therebyform a calk. If it is desired to vary the angle of the calk on the facethereof that is adjacent to the body of the shoe, the operator eitherplaces a face plate 30 of the desired shape on the swage block, or elsetilts the brackets 21 and clamps them in position at the desired angle.

If it is desired to vary the angle of the opposite face of the calk,then the operator tilts the roller supporting frame by means of thelever 4E1. Obviously, by means of the adjustment just described, calksof any desired shape and size may be formed. One of the advantages ofhaving the swage block move both downwardly and forwardly, is that bythis arrangement the machine is antomatically adjusted for shoes ofvarying thickness. lVhen a shoe of great thickness is placed on theblock 12, the downward movement of the swage block is stopped as soon asit strikes the shoe, and there is just enough space left between theworking face of the swage block and the roller to form a calk of theproper thickness, and when a relatively thin shoe is placed upon theblock 12, then the swage block moves downwardly and also forwardly sothat the space between the working face of the swage block and theroller is much less than in the former case, but is exactly proportionedto the requirements of the shoe, and thus a calk is formed which at itsbase is of substantially the same thickness as the shoe.

One of the desirable features obtained by having the swage block placedso that it may be tilted at different angles, is as follows: Assumingthat the swage block is tilted upwardly at its rear end, then it wouldengage the shoe a greater distance from the rear end of the shoe than itwould if left in the position shown in Fig. 5, hence, a calk may beformed of greater thickness at its base than that of the body of theshoe. Hence, by a proper adjustment of the parts herein described, themachine may be set to form horseshoe calks of any desirable size andshape, and the proportions of the calks may be varied relative to thethickness of the shoe.
